Abstract
The utility model relates to a leaf blade gas motor. The utility model is characterized in that rotor permanent magnets are inlaid in the bottom of each slot of rotors, leaf blade magnetic conductors are inlaid in the corresponding parts of one end of each leaf blade inserted in the bottom of each slot and the rotors where the permanent magnets are inlaid, leaf blade permanent magnets are fixedly connected to the leaf blade magnetic conductors by adhesive, and two permanent magnets are vis-a-vis installed in a homopolar way. The utility model has the advantages of simple structure and easy maintenance and manufacture, and can be produced by medium and small sized machine works.
Description
The utility model belongs to the pneumatic motor class.
Vane air motor is that use at present is the most extensive topmost a kind of in the pneumatic gearing, the present gas motor that uses, the blade of motor rises from stator slot, except that by the centrifugal force of blade rotation, mainly adopted following dual mode: 1. utilize the elastic force of the spiral compression spring that is contained in the blade bottom that blade is released; 2 pressurized air that utilize the blade bottom to feed are released blade.The problem that first kind of mode exists is, because the operating rate of gas motor is at 3000 rev/mins to 2500 rev/mins, under long-term periodic loading, spring often destroys because of tired.The problem that the second way exists when blade bottom compressed air pressure is too high, has been quickened the wearing and tearing of blade and stator inner surface.The pressure of bubbling air can not be too high, thereby limited the power and the rotating speed of motor.Pressure is low during starting, and blade easily breaks away from stator inner surface, and it is logical that the high and low pressure air is scurried, and causes motor stall; And the processing of leading to the air flow channel of blade bottom has certain degree of difficulty.
The purpose of this utility model provides a kind of new gas motor, and the blade of this gas motor rises from stator slot, except by the centrifugal force of blade rotation, mainly leans on the repulsion of permanent magnet and permanent magnet homopolar-repulsion.

Below in conjunction with description of drawings structure of the present utility model:
Working principle of the present utility model (figure one), with the working principle of common gas motor is identical, when the A mouth of pressurized air from stator (a1) enters in the active chamber, directive blade (a2), impel blade (a2) to drive rotor (a3) revolution, waste gas is discharged from stator relief opening C, and the residual gas in the cylinder is then discharged by relief opening B.Institute's difference, be that blade (a2) is contained in the structure in rotor (a3) groove, each bottom land at rotor (a3), all be inlaid with rotor permanent magnet (a5), end at the bottom of blade (a2) insertion groove with the relative part that rotor (a3) is inlayed permanent magnet, is inlayed blade magnet case (a7), and being fixed with blade permanent magnet (a6) with binder thereon, two permanent magnets are that homopolarity is installed in opposite directions.For this reason, blade is because the homopolar-repulsion power of two permanent magnets is close in the stator cavity blade all the time.
On rotor, inlay permanent magnet (figure two, figure three),, divide equally plurality of sections, a groove is all arranged on the everywhere, in groove, be fixed with rotor permanent magnet (C2) with briquetting (C3) screw (C4) and binder at the bottom land of rotor (C1).
(figure four, figure five) inlays permanent magnet (b3) on blade, end at the bottom of blade (b1) insertion groove, the relative part of inlaying permanent magnet with rotor, have Baltimore groove thereon, be fixed with blade magnet case (b2) with screw and binder in the groove, then blade permanent magnet (b3) is bonded on the blade magnet case with binder, blade permanent magnet (b3) is installed for homopolarity in opposite directions with rotor permanent magnet (C2).
The employed permanent magnet of the utility model, effect are neodymium-iron preferably---boron (Nd-Fe-B), the magnetizing direction of permanent magnet are radial magnetizing.
Rotor of the present utility model, blade are nonmagnetic substance.
Embodiment of the present utility model (figure six) is the main sectional view of a kind of pair of magnetic blade gas motor.(figure seven) are the M-M sectional view of this kind gas motor.
On main shaft, be fixed with rotor (3), in the groove of rotor (3), be inserted with blade (15), and it is inserted in the stator (2), with preceding sealing cover (4) and back sealing cover (8) and stator location, form active chamber with straight pin (6), bearing (5) is installed at two ends respectively, the body (1) of packing into, cover cover (9),, whole gas motor is installed on one with plug screw (10) and bolt (12), packing ring (11,13); A, B, C are respectively suction port and air outlet, and (14) are the air outlet.In the groove of rotor (3), be inlaid with rotor permanent magnet (18), on blade, be inlaid with blade magnet case (16) and blade permanent magnet (17).
The utility model, simple in structure, be easy to safeguard, easy to manufacture, be applicable to that middle-size and small-size machinery plant produces.
